Claims
- 1. A polarity sensitive grenade firing system for firing independent grenade salvos, comprising:
- (a) first and second grenade salvos;
- (b) a positively polarized relay connected to said first salvo and being wired thereto so that said first salvo can be fired only when said positive relay is energized;
- (c) a negatively polarized relay connected to said second salvo and being wired thereto so that said second salvo can be fired only when said negative relay is energized;
- (d) a power supply capable of providing said system with a positive voltage source or a negative voltage source;
- (e) switch means for selecting between said positive and negative voltage sources, and
- (f) a single control wire connected between said switch means and said relays for carrying power from said power supply to said salvos.
- 2. The invention as claimed in claim 1 wherein said switch means includes a single pole double throw switch.
- 3. The invention according to claim 1 wherein said power supply comprises first and second batteries wired to said switch for supplying current to said system, the positive terminal of said first battery and the negative terminal of said second battery being wired to separate terminals of the switch, the negative terminal of said first battery and the positive terminal of said second battery being connected together and to ground.
- 4. The invention according to claim 1 wherein said salvos are comprised of squibs having ignition systems, said squibs being ignited by said power from said batteries causing normally open contacts of said relays to close and thereby transmit power from said batteries to said ignition system for igniting said squibs.
